SPECIFICATION forming part of Letters Patent No.271,264, dated January30, 1883.

Application tiled October 11, 18852.

To all whom it may ,concern Be it known that I, RUSSELL PHILLIPS, ot

Boston, in the county of Suffolk and State of Massachusetts, haveinvented certain new and .5 useful Improvements in Elevators, of whichthe following is a specification.

My invention relates to freight and passenger elevators, and to safetyattachments for the same, the objects being to lessen the ex- Io penseof running and to increase the safety.

I attain these objects by the mechanism illustrated in the accompanyingdrawings, in whicli- Figure 1 is a side elevation, showing the Iprincipal parts of my elevator. Fig. 2 is a rear elevation of the same.Fig. 3 shows in side elevation that part of the driving-gear and brakedevices that is attached to the elevator-carriage. Fig. 4 is a planview, showing zo that part ofthe driving-gear that is attached to theelevator-carriage. Figs. 5, 6, .7 are views to illustrate the regulatordevice for controlling the descent ofthe elevator.

In the drawings, A represents the platform ofthe elevator-carriage.

A A2 A3 A4 is the frame, attached to the under side of the same, whichserves as a structure for attaching the operating parts.

B3, Figs. 1 and 2, represents a eounterpoise- 3o weight, which isconnected to the four corners -ot the elevator-platform A by means ofropes B B' B B', which pass over pulleys B2 B2.

Attached to the frame of the elevator-carriage is a shaft, F', whichextends entirely across the elevator, and has at each end a pinion, F2.(See Figs. 1 and 4.) These pinions F2 engage with vertical ratchets F3,Figs. 1 and 4. t

F is a grooved pulley running on a shaft, F',

4o which is so arranged that it may revolve without turning the shaftF', or when desirable its revolution will cause the shaft F' to revolve.This is effected by a conical clutch device which connects it with thebevel-gear Wheel F5, the said gear-wheel F5 being rigidly attached tothe shaftF', so that when the grooved wheel F is in clutch-connectionwith F5, then the revolution of F will cause a corresponding revolutionof the shaft F' and the pinions F2,

5o and cause the same to traverse the vertical ratchets F3, Figs. 1 and4, which action causes a corresponding movement ofthe elevatorcar (N0model.)

riage. The grooved wheelF is moved in and out of clutch-connection withthe wheel F5 by means of the collar G, Fig. 4, and lever K10,

vpivoted at K11, this lever K1" being operated by an arm, K9, whichextends radially from the piston-shaft K6, and operates'in an inclinedslot, G2, made in the moving end of the lever K1". (See Fig. 4.) Thegroove wheel F is 60 caused to revolve by the revolution of the ydrive-wheel D,Figs. 1 and 2. This drive-wheel D is supported in suitablehousings, as shown by D2 D2, Fig. 1, and may be driven by steam, water,or other power. Its motion is conimunicated to the groove-wheel F bymeans of the rope D3 D5 D*i DE D9 D1U Dl1 D, which is arranged to passover the several pulleys, H H' H2 H3 H4 H5, (see Fig. 1,) the part D5 D7passing round the groovewheel F, so that any l motion of the rope D3 D,Src., will cause the groove-Wheel F to revolve, and it' the saidgroove-wheel F is in clutch-connection with the shaft F' it will causethe elevator-carriage to ascend.

The drive-Wheel D is provided with an internal gear, Fig. 1which engageswith the Rinion D', by which it may be driven.

E E', Fig. l, is a pawl, which, engaging with the teeth of the internalgear, will prevent the So Wheel D from revolving in the wrong direction.

The moving parts already described are specially designed for raisingthe elevator-carriage, although they may be used, if required, for thepurpose of lowering it; but I do not depend on this part of theapparatus for loWeringthe elevator-carriage, as I have designed specialappliances for regulating the descent of the elevator-carriage, which Iwill now proceed to describe. 9o

The beveled-gear wheel F5 drives a piniongear, F5, (see Figs. 3 and 4,)whichis connected by a clutch and shaft, F", to the crank-disk F8, Figs.3 and 4. This clutch F7 is so arranged that when the elevator-carriageis going up the revolution of the beveled gears F5 Fs will not cause thecrank-disk F8 to revolve; but when the carriage is coming down therevolution of the gears F5 FG will cause the crankdisk F8. to revolve.Hence by reguilating the roo velocity of this crank-disk I can regulatethe velocity of the descent of the elevator-carriage and make the sameperfectly safe. This I accomplish by connecting the crank-disk F3,

il 27L26/1 through the pin L, link L', and pin L2, to the slidingcylinder L3, this cylinder traversing on the piston-rods K6 L4, Fig. 4,said pistonrods K5 L4 having no longitudinal motion. The piston-headwithin the cylinder L3 is compoundthat is, it consists of two perforateddisks L5 K7, the disk L5 being stationary, while the disk K7 may bepartially revolved in connection with its rod K5. lution of the disk K7opens or closes the aperture in the disk L5 in the same manner that anordinary damper or register operates. Con sequently if the cylinder L3is filled with oil or any other suitable liq uid the resistance offeredto its rapid motion may be regulated by turning the disk K7, which, asalready stated, diminishes or enlarges the means of communication fromone end of the cylinder to the other. This adjustment of the disk K7 iseiected by the lever K5, Figs. 3 and 4, said lever being connected tothe shaft K5, as indicated at Figs. 3 and 4, so that by swinging thislever the shaft K5 and disk K7 are operated. This lever K5 may be alsooperated by means of the hand-rope K K' K2K3, Fig. 3, which runs theentire length ofthe well-room, being rigidly attached at both ends tostationary parts of the well-room structure, a part of this. rope alwaysbeing accessible to the occupant of the elevator-carriage. As this ropeK K' K2 K3 passes round a pulley, K4, attached to the handlever K5, itis manifest thatif the said rope is pulled it will draw the lever in thedirection of the arrow R, Fig. 3, and thus operate all of the partscinematically connected to it. This lever K5 is held'back by the springsS, Figs. 3 and'4. I

As an additional safety device for regulating the descent of theelevator, I use a frictionbrake, P, Fig. 3, placed Within a recess orsink- ,age turned in the face of the wheel F5, the end of the brakebearing against the circumscribing outer wall, P', of the recess, and isheld in contact by the indirect action of the springs S and S'When notdrawn out of contact by the movement ofthe lever P3, which is pivoted atP3, Fig. 3, the lever P2 being operated in its turn by a projection atk' formed in the'inner side of the lever K5, so that as the lever K5 isthrown over in the direction of the arrow R its action, through theprojection 7c', against the under side of the lever P2 at the point P4will lift up this end of the lever P2, and thus throw vdown the brake P,connected with its otherend. This partial revov N, Figs. 4 and 7, is atube for furnishing oil for the cylinder L3. (See Figs. 4 and 7.) Thisfeed-tube N (see Fig. 7) is provided with a closing-cap, N', and with acheck-valve, N2, as shown. l claim- Y 1.
